We propose a new hardware ray casting algorithm for unstructured meshes composed of tetrahedral cells. Our work builds on the technique published at IEEE Visualization 2003 by Weiler et al.. Our… (More)

The parallel vectors (PV) operator is a feature extraction approach for defining line-type features such as creases (ridges and valleys) in scalar fields, as well as separation, attachment, and… (More)
The recent development of graphics hardware is presenting a change in the implementation of the graphics pipeline, from a fixed set of functions, to userdeveloped special programs to be executed on a… (More)

Traditional shadow maps store a single depth value per cell, leading to a binary outcome by the shadow test (either lit or in shadow), and are prone to produce aliased shadow borders. We present a… (More)

Direct visualization of higher-order data avoids the error and overhead introduced by the widely used resampling approach. Here, we give an overview of problems and solution strategies in the context… (More)
The hp-adaptive finite element (FE) method is a discretization scheme which is increasingly finding application in numerical solvers. Most existent visualization tools, however, are based on linear… (More)
